Energy Absorbing Manholes
Energy Absorbing Manhole Benefits
Fiberglass energy absorbing manholes play a critical role in water management systems. Industrial companies are choosing these items for several reasons, including their following advantages:
- Replaces the need for costly line excavations and resloping
- Installation can be performed at the same time with a packaged metering manhole
- The ability to reduce labor and machine/equipment installation costs
- Interior is smooth, resistant to corrosion, and durable for years to come
Additionally, all TRACOM energy absorbing manholes are built to exceed all industry standards, including ASTM D3753 and AASHTO H-20.
Options and Accessories for your Energy Absorbing Manhole
